Randomise anything

I recently wanted to present some Vimeo hosted videos in my site. Vimeo allows us to create albums which are basically a collection of videos presented in one flash driven player. The problem is that albums do not play in mobile devices. As the videos were over 30, loading them all individually would be too much for some devices and as we did not want to make a selection, I was looking for a way to randomly load that content.

The solution was simple as txp:linklist came to the rescue.

In the link description field add the number of the video as generated by vimeo.

<txp:linklist category="my_link_list_video_category" limit="4" sort="rand()" wraptag="">
<iframe src="http://player.vimeo.com/video/<txp:link_description escape="" />?title=0&amp;byline=0&amp;portrait=0" width="229" height="172" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>

The code above could be adapted to randomise anything. For example if someone wishes to have some random quotes using the html5 standard, the code could become:

<txp:linklist category="my_link_list_quotes_category" limit="1" sort="rand()" wraptag="" />
<txp:variable name="linkurl" value='<txp:link_url />' />
<txp:if_variable name="linkurl" value="">
<blockquote><txp:link_description escape="" />
<cite><txp:link_title /></cite></blockquote>
<txp:else />
<blockquote cite="<txp:variable name="linkurl" />"><txp:link_description escape="" />
<footer><a href="<txp:variable name="linkurl" />" rel="external"><txp:link_title /></footer></blockquote>
